In the 1970s, the Yellow River Conservancy Commission of the Ministry of Electric Power and Water Resources organized Yellow River Conservancy Commission of the Yellow River Conservancy Commission to carry out collaborative experimental research on the scientific research units in the six provinces (autonomous regions) of the Yellow River in order to speed up the control of sloping farmland, change the drought and low yield, After 10 years’ exploration, according to the natural features of each province (district), the technical problems such as planning, design and construction of the mechanical terrace have basically been solved.
